.NET Core and App.config?

I’m building a .NET Core app with the AWS SDK, although I believe this problem is within .NET Core and not the AWS SDK.

Unlike a .NET Console or WinForms project type in Visual Studio, the .NET Core console project type does not seem to include an App.config file. So I manually added one, but either .NET Core itself, or the build process does not seem to be recognizing the App.config file since it can’t seem to make use of any of the settings I specify.

Is there something else I need to do to get .NET Core to use an App.Config file like the .NET Framework apps do?
